Bitcoin and Ethereum options with a nominal value of 9.87 billion USD will be settled upon expiration

Greeks.live macro researcher Adam posted on platform X to announce options expiration data: 1. 109,000 BTC options expired, Put Call Ratio was 0.93, maximum pain point at $72,000, notional value of $8.55 billion. 2. 563,000 ETH options expired, Put Call Ratio was 0.72, maximum pain point at $2,200, notional value of $1.32 billion.This week the market continued to rebound, with Bitcoin strongly breaking through $78,000. The Web3 conference in Hong Kong was also filled with a joyful atmosphere of rising prices, and altcoin markets are warming up. This is a monthly expiration, with 25% of options set to expire. In terms of holding period, the distribution of open contracts in the options market shows 12% at the end of May and 24% at the end of June. From the main options data, Bitcoin's main term implied volatility (IV) has continued to decline this month, with most term IVs dropping by 1% to 2%, falling below 40%, while ETH's main term IV has decreased even more, currently around 60%.Despite the price increase, the Skew has retreated, and the market does not exhibit FOMO sentiment. In the second quarter of this year, Bitcoin performed significantly better than in the first quarter in terms of both price and popularity. This month's continued rebound is a sign of capital inflow; if macro pressures bottom out by mid-year, then Bitcoin's bottom will also be confirmed.

Tether confirms cooperation with the U.S. government to freeze over $344 million worth of USDT

Tether announced that it has supported the U.S. government's freeze of over $344 million USDT, involving two wallet addresses. This freezing action was carried out in collaboration with the U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) and U.S. law enforcement agencies, aimed at preventing further movement of funds.The freeze was based on information provided by multiple U.S. law enforcement agencies, linking these addresses to illegal activities. Tether stated that when wallet addresses are associated with sanctions evasion, criminal networks, or other illegal activities, the company will take freezing measures. This has now become Tether's routine response to legitimate requests from U.S. and global law enforcement agencies.Tether CEO Paolo Ardoino stated, "USDT is by no means a safe haven for illegal activities. We take immediate action when there are credible links to sanctioned entities or criminal networks. Recent events have shown what can happen when platforms fail to act swiftly, law enforcement fails, users are exposed, and trust is lost. Our approach is different; we combine blockchain transparency, real-time monitoring, and direct coordination with law enforcement agencies to prevent the flow of funds. This is a responsibility we take very seriously as one of the largest issuers in the market."This action is part of Tether's cooperation with U.S. law enforcement agencies. The U.S. Department of Justice had previously confirmed Tether's support in law enforcement actions, successfully seizing nearly $61 million and approximately $225 million in "pork scam" funds.

Coinbase: Ethereum, Solana, and other PoS chains may face quantum risks

According to Decrypt, Coinbase's Quantum Computing and Blockchain Independent Advisory Committee released a report on Tuesday stating that proof-of-stake (PoS) blockchains may face a greater risk of exposure to future quantum computing attacks, as the cryptography relied upon by the validator signatures that protect these networks could ultimately be cracked by sufficiently powerful quantum computers. The report points out that PoS networks like Ethereum and Solana rely on cryptographic signatures—Ethereum validators use BLS signatures, while Solana validators and users use Ed25519 signatures—to help the network reach consensus on blocks and maintain consensus.The advisory committee stated, "PoS chains have exposure risks in the signature schemes used by validators to protect the network, which means that the challenges faced by PoS are not just about upgrading wallets; parts of the core consensus mechanism itself may need to be redesigned." The report mentioned recent work by Ethereum developers, including a proposal by co-founder Vitalik Buterin in February to replace BLS validator signatures, KZG commitments, and ECDSA wallet signatures with quantum-resistant alternatives.The committee also listed the digital signatures used in cryptocurrency wallets as another major long-term vulnerability, estimating that about 6.9 million bitcoins belong to the category where the public keys are already visible on-chain. The report stated that the current cryptocurrency system remains secure, as quantum computers capable of breaking modern cryptographic signatures do not yet exist.
